Gorilla discrimination.
These movies are kinda apeist.
Gorillas are always depicted as big brutish henchman. Bad guys. The muscle. Why aren't there any female ones? Why can't some of them be smart and kind?
Chimpanzees are assholes and nastier than Gorillas. Their representation in these movies is diverse. The good guys, smart guys, bad guys, male, female, young and old. They cover the whole spectrum and are by far the most represented apes in these movies.
Orangutans get treated like MENSA monks in these things! You only see a couple of them and they're absolute saints.
